Couldn't find any pointers in the Apple docs (other than that the two types appear not to be toll-free bridged), and amazingly searching in cocoabuilder on "CGColor" yields no results at all. Nada. So no info on converting an NSColor to a CGColor. Googling for these two words yields no usable results either, so hence the question here: What is the best/easiest way to convert an NSColor to a CGColor?


I also bumped into this problem recently and ended up implementing this function:


static CGColorRef CGColorCreateFromNSColor (CGColorSpaceRef colorSpace, NSColor *color)
{
NSColor *deviceColor = [color colorUsingColorSpaceName: NSDeviceRGBColorSpace];

float components[4];
[deviceColor getRed: &components[0] green: &components[1] blue: &components[2] alpha: &components[3]];


	return CGColorCreate (colorSpace, components);
}


That I call like this:


CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB (); CGColorRef cgColor = CGColorCreateFromNSColor (colorSpace, nsColor); CGColorSpaceRelease (colorSpace); // Do stuff with cgColor CGColorRelease (cgColor);
